To all whom it may concern."

Be it known'that I, FRIEDRICH 'CLnMENs KAUBISGH, citizen of Germany, residing at. Freital-Zaukerode, in the State of Saxony, and Republic of Germany, have invented certain new and useful Improvements in and nne t d wit gar tt M h nes, o which the following is a specification.

The invention relates exclusively to those cigarette tube machines in which acontinuons tube rod is formed which [is fed forward uninterruptedly. In such machines it as h he to en s a to ecip i h longitudinal direction of the rod the sheath on whichthe cigarette tubesevered from the rod,is placed. The sheath was first moved towards the rod, which travelled to meet it, and passed into theend of the rod. At the. same time the cigarette tube wassevered from the rod by cutting means which was also reciproc'ated in the direction of the rod, and during the cutting (operation moved with the speed of the rod in the direction of feed. The sheath was then. retracted with the tube thereonat a considerably higher velocity than that of the feed of the'rod. On the return movement the mouthpiece coil was inserted andthe tube with the coil introduced stripped from the" sheath or beak.

It is clear that with this known arrangement the sheath or beak must reciprocate in a path of considerable length, which will vary with the variable length of cigarette. In consequence the sheath and the parts carrying it must be moved over an extended path and over part of such path at a very igh speed, which in modern high-speed machines has led to unacceptable conditions as regards the movement of masses and the stresses on the operating devices.

It is also clear that in the earlier arrangements of the, tube rod, a considerable length of the rod between the point where it leaves the means for closing the rod and support ing it, and the point at which it engages with the sheath, must be left without support. It must be remembered that severing means must be interposed which must move to and fro and which would not permit of the provision within the region of its movement of a stationary guide tube or the like.

Moreover, the sheath reciprocates to and fro and cannot be arranged nearer the severing device than the imensions of the cigarette tube will permit. In consequence the free end of the tube rod in deflected by external influences as, for instance, by a drau htof air, from its path and consequently oes not exactly fit over the sheath which is reciprocated ,in the direction of the central axis of the rod. As a result waste cigarettes are produced and the operation of the machine is disturbedi In accordance with the present invention the cigarette tube severed from the rod first passes, between pairs of profiled rollers, which rotate about stationary axes,,which rollers frictionally engage and feed the tube forward. The pair ofrollers run at such a speed that the tube is separated from the rod and is fed forward to the sheath at a spfied considerably in excess of that of the re I The sheath. therefore, now need he moved only to a slight extent so that the movement of masses is reduced and the operating means not excessively stressed. Further, the cigarette tube may be completely slipped over the sheath so that the distance between the means for stripping the tube from the sheath and the sheath itself may be quite small. The shock produced on the tr pp r conta -ins h t tube is thu re duced so that damage to the tubeend, hitherto usual, is avoided. In addition, the free end of the tube rod is supported by the feeding rolls and a stationary guide tube or the like may be interposed between the severing device and the feeding rollers for supporting the end of the rod.

The new machine is illustrated in the ac companying drawing which shows the parts necessary for an understanding of the invention.

Figs. 1 and 2 being side views with the rod in different positions, while Fig. 3 is a front elevation of the feeding rollers.

As shown, the cigarette tube rod a is moved continuously forward in the direction of the arrow. It passes between the open shanks b, c, ofthe severing device and into the stationary guide tube (Z, the opening of which is widened and slightly rounded off so as to receive smoothly the end of the rod. Thereafter the rod passes between the pair of profiled rollers e, f, and then between a second pair 9, 71. The rollers are mounted in the wall A of the frame and carry adja cent the wall driving pinions z', the pinions of the associated profile rollers being in mesh. The upper pinions 2' are driven by a common spur wheel 70, on the axis of which is mounted pulley Z which is driven from a pulley m on the driving shaft a by a belt m. As soon as the forward end of the tube rod (6 passes int-o engagement with the first pair of rollers e, f, the cigarette tube 0 is severed from the rod by the severing device and moved during the severing operation with the speed of the rod in the direction of feed. The pairs of rollers e, f, and g, h, are driven in such manner that they feed the cigarette tube 0 forward at a speed considerably erceeding that of the cigarette rod.

The tube 0 fed forward by the pair of rollers is given up to the sheath 7), which re ciprocates in the direction of the axis of the tube or of the cigarette tube rod. As the work of separating the tube from the rod and the increased movement is already provided for by the pair of rollers, the movement of the sheath may be considerably shorter than heretofore.

I claim 1. In a cigarette tube forming machine, the combination with a continuous cigarette tube fed with constant speed, the severing device and a sheath for facilitating the passing of a mouthpiece into the severed cigarette tube section, of guide members interposed between said severing means and sheath and adapted to feed the severed tube section with greater speed toward said sheath than the speed of the continuous tube, for the purpose specified.

2. In a cigarette tube forming machine, the combination with a continuous ciga rette tube fed with constant speed, the severing device and a sheath for facilitating the passing of a mouthpiece into the severed cigarette tube section, of rotary guide members interposed between said severing means and sheath and adapted to feed the severed tube section with greater speed toward said sheath than the speed of the continuous tube, for the purpose specified.

3. In a cigarette tube forming machine, the combination with a continuous cigarette tube fed with constant speed, the severing device and a sheath for facilitating the passing of a mouthpiece into the severed cigarette tube section, of two pairs of grooved rotary feed rollers having stationary axes and interposed between said severing means and sheath and adapted to feed the severed tube section with greater speed toward said sheath than the speed of the continuous tube, for the purpose specified.

4. In a cigarette tube forming machine, the combination with a continuous cigarette tube fed with constant speed, the severing device and a sheath for facilitating the passing of a mouthpiece into the severed cigarette tube section, of two pairs of grooved rotary feed rollers having stationary axes and interposed between said severing means and sheath and adapted to feed the severed tube section with greater speed toward said sheath than the speed of the continuous tube, and a stationary guide between said severing means and said feed rollers, for the purpose specified.

In testimony whereof I affix my signature.
